Title: Lens adjustment tool for CCTV cameras that can prevent damage to the lens module
Inventor: KIM YOUNG YI
IPC: H04N5/225
Filed: 2021-03-31
Abstract: The present invention relates to a CCTV camera lens adjustment tool capable of preventing damage to a lens module in a CCTV camera for constantly monitoring or checking a space where a manager does not reside and, more specifically, to a CCTV camera lens adjustment tool capable of preventing damage to a lens module. In the lens module of a CCTV camera, a gear ring coupled to a zoom ring and a focus ring is rotated by a separate lens control shaft. A crown gear is formed on the bottom surface of the lens control shaft to couple a drive gear capable of freely rotating from the lens control shaft. A spring-loaded stepping gear from the lens control shaft is coupled to a lower side of the drive gear in a non-rotating lifting manner. Thus, while the rotational force of the lens control shaft is transmitted to the gear ring by the meshing force of the drive gear and a transmission gear, the stepping gear descends to block the rotational force of the lens module when a load by which the rotating angle of the lens module is exceeded occurs. Therefore, the CCTV camera lens adjustment tool can prevent breakage or damage to various gears and remove the rotational force of a load applied to the lens module, thereby preventing the lens module from being damaged.
